We're sorry to hear this, as our Febreze PLUG Scent Booster goes through strict quality checks to ensure that you can get the best possible results. If there's no scent coming out at all, we suggest making sure that the refills are fully and properly inserted into the device. As well, make sure the device is set to either Low, Medium, or High, and not in the middle. We hope this helps, but please give us a call at (800) 308-3279 if you'd like further assistance.
